CHARLES R. NELSON, or NEW YORK, N. Y.

WlNDOW-BEAD FASTENER.

SPECIFICATION forming part of Letters Patent No. 338,433, dated March23, 1886.

Application filed December 5, 1885. Serial No. 184,810. (No model.)

To ctZZ whom it may concern:

Be it known that I, GHARLEs R. NELSON, of the city, county, and State ofNew York, have invented a new and Improved Bead- Fastener, of which thefollowing is a full, clear, and exact description.

The object of my invention is to provide a new and improvedbead-fastener for holding stop-beads on window-frames in place in such amanner that they can easily be adjusted on the frame to have the properposition in relation to the sashes, thus preventing rattling of thesashes.

The invention consists in the construction and combination of parts anddetails, as will be fully described hereinafter, and then pointed out inthe claim.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is aface view of part of a stop-bead provided with threedifferent constructions of my improved bead-fastener. Fig. 2 is a sectional View of the same on the line y 3 Fig. 1. Fig. 3-is a sectionalview of the same on the line it as, Fig. 1. Fig. 4 is asectional view ofthe same on the line 2 a, Fig. 1. Fig. 5 is a sectional view of the sameon the line 10 w, Fig. 1.

The stop-bead A is provided with a series of circular apertures, B,through which screws 1) can be passed into the sides of the windowframe0, on which the said bead is to be held, the diameter of the aperturesbeing about equal to three times (more or less) the diameter of thescrews, so that the bead can be shifted in all directions a shortdistance without changing the position of the screws. On the outersurface of the stop-bead a washer, E, is placed over each aperture B,and through the said washers the screws are passed.

The washers may have rounded edges, as shown in Fig. 3, or bevelededges, as shown in Fig. 4, and the heads of the screws maybe rounded, asshown in Figs. 3 and 4, or they may be flat, as shown in Fig. 5, and thewasher may be provided with a countersink for receiving the said flathead of the screw, as shown in Fig. 5. The screws may also be providedwith square or ornamental heads, and the washers may also be madeornamental.

Some of the different positions of the bead in relation to the screwsare shown in Figs. 3, 4, and 5.

As the apertures in the bead are circular, they can be moved at rightangles to its longitudinal axis, in the direction of its longitudinalaxis, and diagonally up or down,without "requiring any changes in thepositions of the screws. The washers always cover the apertures B, andthus it cannot be seen whether the screws are at the center of theapertures or out of the same.

It frequently happens that the carpenter does not make the screw-holesin the windowframe exactly in the center of the apertures B, and inorder to remedy this defect fresh holes must be made in the frame topermit of fitting the beads nicely. If the beads are provided with thecircular apertures, as described abovo, they can be adjusted nicelywithout requiring any fresh holes.

The special advantages of my improved bead-fastener are its greatsimplicity and its facility of adjustment. The bearing-surfaces of theunder sides of the washers being five times as great as thebearingsurfaces of-the under sides of the heads of the screws it isevident that by applying my improved fastener the bead is held morefirmly, and all movement of the head is prevented when the sash israised or lowered.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- Thecornbination, with a stop-bead having circularapertures, of washers placed over the apertures, which washers cancompletely cover said apertures, and of screws passed through thewashers and the apertures into the casing,

the diameter of the screws being equal to about one-third of thediameter of the apertures to permit of moving the bead slightly in alldi rections without changing the positions of the screws, substantiallyas herein shown and described.

CHARLES R. NELSON.
